Abstract

3D printing technology provides a new solution for the rapid prototyping of mechanical parts, breaking through the limitations of traditional manufacturing methods in structural complexity, process flow, and material utilization. Systematic analysis shows that this technology offers significant advantages in the production of complex structural components, while the forming quality is comprehensively influenced by material properties, equipment performance, process parameters, environmental conditions, and post-processing techniques. Practical printing cases of typical mechanical parts have verified their feasibility in terms of dimensional accuracy, mechanical properties, and functional realization. These findings provide theoretical support and technical basis for promoting 3D printing from rapid prototyping to mass production, and also inject new momentum into the development of intelligent manufacturing.
